But most scientists seem to think there was minimum contact with the outside world after the first arrival. Personally I think there were actually several waves of settlement. <br /><br />&quot;And wasn&#39;t Mungo man&#39;s mt DNA considered to be unrelated to any modern humans?&quot; <br /><br />Again true. However the finding has been questioned by many. On the other hand even if the original conclusion was correct that line of mt-DNA could have since died out. Other lines still present in Australia were found in the same study: <br /><br />http://www.google.co.nz/url?sa=t&amp;rct=j&amp;q=&amp;esrc=s&amp;source=web&amp;cd=1&amp;ved=0CEkQFjAA&amp;url=http%3A%2F%2Fwww.pnas.org%2Fcontent%2F98%2F2%2F537.full.pdf&amp;ei=bMwoUJ6tD5GeiAfLooHwDQ&amp;usg=AFQjCNH6_uizewzHi6KC7qpuFsg-JrZ76Aterrythttp://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-55438906847239745612012-08-13T09:06:02.355+03:002012-08-13T09:06:02.355+03:00terryt, why do we have to suppose that present-day...terryt, why do we have to suppose that present-day Aborigines descend from the earliest arrivals? <br />And wasn&#39;t Mungo man&#39;s mt DNA considered to be unrelated to any modern humans? aramthttp://www.blogger.com/profile/04486006044411081900noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-91571558949399775402012-08-13T05:02:53.503+03:002012-08-13T05:02:53.503+03:00&quot;Whether transmission of new behavioral innov...&quot;Whether transmission of new behavioral innovations was cultural or genetic&quot; <br /><br />My guess is a bit of both. <br /><br />&quot;From this study it is proposed that the MP-UP transition for this site can be placed immediately after 45,200 ± 700 14C years BP and before 43,600 ± 600 14C years BP or from 49/48 to 47/46 radiocarbon calibrated years before present (years Cal BP)&quot;. <br /><br />And that is more recent than the most likely time of first arrival in Australia. So that transition can hardly be used to define &#39;modern human, unless we&#39;re going to exclude Australian Aborigines from that term.terrythttp://www.blogger.com/profile/17327062321100035888noreply@blogger.comtag:blogger.com,1999:blog-7785493.post-78961001219595955762012-08-12T17:36:50.951+03:002012-08-12T17:36:50.951+03:00Dieneke

Thus the explosion in exploration of Art, Music etc. Aswell as curiosity about what is over the mountain.<br />Or more precisely, since it seems that this happened more than once, the invention of the ability to teach others how to do this.aeoliushttp://www.blogger.com/profile/09528717028785728695noreply@blogger.com
